You seem incredibly angry at the world, maybe justly, we cannot say as obviously we have not got access to the full facts.
You also seem intent on blaming everyone but yourself for your situation and your daughter's removal. Your father, your in laws, the system.
Child removal usually involves assessments of the stability of the home and capability of the parents, no matter which country you're in this is pretty standard. Judges make decisions based on those assessments not on accusations of drug usage with no evidence.
I understand you had PND and were lacking support. You sound like you may have been homeless as you lost the house and your parents were away?
But yet I would say you're still unable to provide a stable home for a child and stand on your own two feet since you are back living with your parents who you don't seem to even like.
The age of the child then and now make a difference as to whether it would be in their best interests NOW to be removed and placed back with you, irrespective of any wrongdoing in the past. You may be able to seek redress for any malpractice in the past if your child was taken away without due cause however it is irrelevant to a court decision today.
If you want to even try for your daughter back you need to present a case of why it is in her best interests, without any reference to how wrong everyone else was. Treat them as separate issues. You need to show how you are the more stable option and how being with you is best for her. I'm not convinced you will be able to tbh.
